Shar's revenge on K-fed and Britney.

This sounds crazy but the New York Post is reporting that at a birthday party for Brandy's brother Ray J., Shar Jackson aka Kevin Federline's baby mama, hooked up with Britney Spears' former husband-for-a-day Jason Alexander. You may remember Alexander from the infamous 55 hour marriage to Britney in 2004...payback is such a bitch lol...also of note at the party was of course Brandy with new boyfriend Nick Cannon...say it ain't so.
